How many hard drives wake up on SMB share access?

[nasuser3344]

The background to my question is that I wish to prevent unnecessary spin ups of my harddrives by placing the most often needed files on the SSD (along with the OS).

I'm wondering if the following scenario would work:
Disk 1: SSD with QNAP OS
Disk 2,3,4: harddrives

All drives are configured as static single volumes and after the specified time they actually all go to sleep.
If I then access only the share on the SSD via UNC path like \\qnap\shareOnSSD will the other drives spin up too? Is the NAS waking up all drives on any SMB access?
I have no other mounted drives or PCs accessing the qnap.

Since you have it configured, can't you test it to find out? I would assume that only the drive being accessed would spin up, but can't test it myself as a) I disabled spin down and b) all my drives are in a raid array.

At the time of writing I did not have it configured. But in the meanwhile I tested it and it works!
